(JavaScript) Socket/SSL/TLS through SOCKS5 / SOCKS4 Proxy

Demonstrates how to use the Chilkat Socket/SSL/TLS component/library with a SOCKS5 or SOCKS4 proxy server.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var socket = new CkSocket();

// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to calling Connect.  The connection may be SSL/TLS or 
// non-secure - both will work with a SOCKS proxy.
// The SOCKS hostname may be a domain name or 
// IP address:
socket.SocksHostname = "www.mysocksproxyserver.com";
socket.SocksPort = 1080;
socket.SocksUsername = "myProxyLogin";
socket.SocksPassword = "myProxyPassword";
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
socket.SocksVersion = 5;
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Connect to port 5555 of 192.168.1.108.
// hostname may be a domain name or IP address.
var hostname = "192.168.1.108";
var ssl = false;
var maxWaitMillisec = 20000;
success = socket.Connect(hostname,5555,ssl,maxWaitMillisec);
if (success !== true) {
    console.log(socket.LastErrorText);
    return;
}

// Set maximum timeouts for reading an writing (in millisec)
socket.MaxReadIdleMs = 10000;
socket.MaxSendIdleMs = 10000;

// The server (in this example) is going to send a "Hello World!" 
// message.  Read it:
var receivedMsg = socket.ReceiveString();
if (socket.LastMethodSuccess !== true) {
    console.log(socket.LastErrorText);
    return;
}

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
success = socket.Close(20000);

console.log(receivedMsg);
